OMEGA(1)               DragonFly General Commands Manual              OMEGA(1)

NAME
       omega, iniomega, viromega - extended unicode TeX

SYNOPSIS
       omega [options] [commands]

DESCRIPTION
       This manual page is not meant to be exhaustive.  The complete
       documentation for this version of TeX can be found in the info file or
       manual Web2C: A TeX implementation.

       Omega is a version of the TeX program modified for multilingual
       typesetting.  It uses unicode, and has additional primitives for (among
       other things) bidirectional typesetting.

       The iniomega and viromega commands are Omega's analogues to the initex
       and virtex commands.  In this installation, they are symlinks to the
       omega executable.

       Omega's command line options are similar to those of TeX.

       Omega is experimental software.

OPTIONS
       This version of Omega understands the following command line options.

       --fmt format
              Use format as the name of the format to be used, instead of the
              name by which Omega was called or a %& line.

       --help Print help message and exit.

       --ini  Be iniomega, for dumping formats; this is implicitly true if the
              program is called as iniomega.

       --interaction mode
              Sets the interaction mode.  The mode can be one of batchmode,
              nonstopmode, scrollmode, and errorstopmode.  The meaning of
              these modes is the same as that of the corresponding \commands.

       --ipc  Send DVI output to a socket as well as the usual output file.
              Whether this option is available is the choice of the installer.

       --ipc-start
              As --ipc, and starts the server at the other end as well.
              Whether this option is available is the choice of the installer.

       --kpathsea-debug bitmask
              Sets path searching debugging flags according to the bitmask.
              See the Kpathsea manual for details.

       --maketex fmt
              Enable mktexfmt, where fmt must be one of tex or tfm.

       --no-maketex fmt
              Disable mktexfmt, where fmt must be one of tex or tfm.

       --output-comment string
              Use string for the DVI file comment instead of the date.

       --progname name
              Pretend to be program name.  This affects both the format used
              and the search paths.

       --shell-escape
              Enable the \write18{command} construct.  The command can be any
              Bourne shell command.  This construct is normally disallowed for
              security reasons.

       --version
              Print version information and exit.

ENVIRONMENT
       See the Kpathsearch library documentation (the `Path specifications'
       node) for precise details of how the environment variables are used.
       The kpsewhich utility can be used to query the values of the variables.

       One caveat: In most Omega formats, you cannot use ~ in a filename you
       give directly to Omega, because ~ is an active character, and hence is
       expanded, not taken as part of the filename.  Other programs, such as ,
       do not have this problem.

       TEXMFOUTPUT
              Normally, Omega puts its output files in the current directory.
              If any output file cannot be opened there, it tries to open it
              in the directory specified in the environment variable
              TEXMFOUTPUT.  There is no default value for that variable.  For
              example, if you say tex paper and the current directory is not
              writable, if TEXMFOUTPUT has the value /tmp, Omega attempts to
              create /tmp/paper.log (and /tmp/paper.dvi, if any output is
              produced.)

       TEXINPUTS
              Search path for \input and \openin files.  This should probably
              start with ``.'', so that user files are found before system
              files.

       TEXEDIT
              Command template for switching to editor.  The default, usually
              vi, is set when Omega is compiled.

FILES
       The location of the files mentioned below varies from system to system.
       Use the kpsewhich utility to find their locations.

       omega.pool
              Encoded text of Omega's messages.

       *.fmt  Predigested Omega format (.fmt) files.

BUGS
       This version of Omega fails to trap arithmetic overflow when dimensions
       are added or subtracted.  Cases where this occurs are rare, but when it
       does the generated DVI file will be invalid.

       The DVI files produced by Omega may use extensions which make them
       incompatible with most software designed to handle DVI files.  In order
       to print or preview them, you should use odvips to generate a
       PostScript file.
